PORTABLE ABUTMENT FOR AUTOMATIC TRAIN-STOPS.-

Specification of Letters Patent.

Patented May 2%), 1917.

Application filed June 2, 1916. Serial No. 101,398.

To all whom it may concern:

Be it known that 1, CHARLES A. WVILLARD, a citizen of the United States, residing at Madison, in the county of New Haven and State ofConnecticut, have invented a new and useful Improvement in Portable Abutments for Automatic Train-Stops; and I do hereby declare the following, when taken in connection with the accompanying drawings and the characters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this application, and rep resent, in

Figure 1 a top or plan view of a portable abutment for automatic train stops constructed in accordance with my invention.

Fig. 2 a side view of the same shown in an operative position.

Fig. 3 a side view of the device in folded position.

This invention relates to an improvement in portable abutments for automatic train stops in which a motor is provided with a lever extending downward from a valve which lever is adapted to be moved by striking an abutment between the rails so as to apply the brakes or signal the engineer at danger points. At certain points fixed abutments are provided which may be raised into the path of the lever on the engine when it is desired to stop a train.

The object of this invention is to provide a simple portable device which may be readily placed in position by the brakeman or signal-man of a train to stop a succeed ing train; and the invention consists in the construction and arrangements of parts as hereinafter described and particularly recited in the claims.

In carrying out my invention, I employ two bars 4, 5; the end of the bar 4: is pivotally connected to the bar 5 as at 6 so that when folded together the end of the bar 5 will project beyond the end of the bar 4. The ends of these bars are provided with insulating blocks 7 adapted to engage with the webs 8 of rails 9 and preferably the lower edges of the bars will be provided with insulated springs 10 which bear upon the flanges 11 of the rails so as to force the bars upward. The bar 5 is formed with a notch 12 adapted to pass over a pin 13 projecting outward from the side of the bar and preferably the upper edge of this pin will be beveled. Secured to the bar 5 is a latch casing 14: containing a beveled nose latch 15 normally forced outward by a spring 16 and projecting into the notch 12 and in position to engage with the pin 13' before the pin enters the notch 12. The bars 4: and 5 are also provided with upwardly projecting abutments 17 adapted when the bars are in place between the rails to stand in the path of levers depending from train valves. In case a train has been stopped between signal points the trainman or brakeman of the train stopped will carry this portable abutment back a suitable distance and set it in position between the rails by opening the bars and forcing their inner ends downward so that the pin 13 on one bar will pass the latch 15 on the other bar and. enter the notch 12 so that the bars will be locked in their open position. When thus placed the abutments 17 project upward and stand in the path of the train levers so as to operate the lever of a following train. The bolt may be provided with an operating handle 18 by which the bolt is conveniently retracted when it is desired to remove the abutments. When folded together, the de vice is readily transported, the abutment 17 forming a handle by which it may be conveniently carried.

I claim '1. A portable abutment for automatic train stops comprising two bars pivotally connected together the upper edges of said bars provided with upwardly projecting abutments, and means for locating the bars between the opposite rails of a railroad.

2. A portable abutment for automatic train stops comprising two bars pivotally connected, said bars provided at their outer ends with insulating blocks, said bars provided with abutments projecting upward from their upper edges, and means for looking the bars in their open position.

3. A portable abutment for automatic train stops comprising two bars pivotally connected together, the end of one bar proj ecting beyond the end of the other bar, said projecting end formed with a notch, the other bar provided with a pin adapted to enter said notch, and means for holding the pin in the notch when the bars are in their open position.

4. A portable abutment for automatic train stops comprising two bars pivotally connected together, said bars provided at their outer ends with insulating blocks, and

with springs projecting below the lower said projecting end formed with a notch, a 10 edge of said bars, said bars provided with pin on the other bar adapted to enter said abutments projecting upward from their upnotch, a latch mounted on the projecting end per edges, and means for locking said bars of the bar and extending across the open side in their open osition. of the notch and adapted to engage with 5. A porta 1e abutment for automatic said pin to hold the same in the notch when 15 train stops, comprising two bars pivotally the bars are in the open position. connected together, the end of one bar projecting beyond the end of the other bar, CHARLES A. VILLARD.
